ABOUT THIS PROSPECTUS

This prospectus is part of an automatic shelf registration statement that we have filed with the U.S. Securities and Exchange Commission (the "SEC") as a "well-known seasoned issuer" (as defined in Rule 405 under the Securities Act of 1933, as amended (the "Securities Act")) using an automatic "shelf" registration process.

DESCRIPTION OF DEBT SECURITIES AND GUARANTEES

In this description, references to "holders" mean those who own debt securities and the related guarantees registered in their own names, on the books that the registrar maintains for this purpose, and not those who own beneficial interests in debt securities and the related guarantees registered in "street name" or issued in book-entry form and held through one or more depositaries.

The following description, together with the additional information we include in any applicable prospectus supplement or free writing prospectus, summarizes certain general terms and provisions of any senior debt securities that Accenture Capital may offer (the "Accenture Capital debt securities"), any senior debt securities that Accenture DAC may offer (the "Accenture DAC debt securities") or that Accenture Capital and Accenture DAC may offer as co-issuers (the "co-issued debt securities") pursuant to this prospectus. When we offer to sell a particular series of debt securities, we will describe the specific terms of the series in a supplement to this prospectus. We will also indicate in the applicable prospectus supplement to what extent the general terms and provisions described in this prospectus apply to a particular series of debt securities.

Accenture Capital Debt Securities

Accenture Capitalmay issue Accenture Capitaldebt securities under an indenture to be entered into later (the "Accenture Capital indenture"), among Accenture Capital, as issuer, and Accenture plc, as guarantor (the "guarantor"), and The Bank of New York Mellon Trust Company, N.A. or another trustee, as trustee, in respect of certain series of Accenture Capitaldebt securities.

Any Accenture Capitaldebt securities that Accenture Capitalissues under the Accenture Capitalindenture will constitute unsubordinated debt of Accenture Capital. Any guarantee that Accenture plc, as the guarantor, issues under the Accenture Capitalindenture will constitute an unsubordinated obligation of Accenture plc.

Accenture DAC Debt Securities

Accenture DAC may issue Accenture DACdebt securities under an indenture to be entered into later (the "Accenture DAC indenture"), among Accenture DAC, as issuer, and Accenture plc, as guarantor, and The Bank of New York Mellon Trust Company, N.A. or another trustee, as trustee, in respect of certain series of Accenture DACdebt securities.

Any Accenture DAC debt securities that Accenture DAC issues under the Accenture DAC indenture will constitute unsubordinated debt of Accenture DAC. Any guarantee that Accenture plc, as the guarantor, issues under the Accenture DAC indenture will constitute an unsubordinated obligation of Accenture plc.

Co-Issued Debt Securities

Accenture Capital and Accenture DAC may jointly issue co-issued debt securities under an indenture to be entered into later (the "joint indenture"), among Accenture Capital, as co-issuer, Accenture DAC, as co-issuer, Accenture plc, as guarantor, and The Bank of New York Mellon Trust Company, N.A. or another trustee, as trustee, in respect of certain series of co-issued debt securities.

Any co-issued debt securities that Accenture Capital and Accenture DAC jointly issue under the jointindenture will constitute unsubordinated debt of Accenture Capital and Accenture DAC. Any guarantee that Accenture plc, as the guarantor, issues under the joint indenture will constitute an unsubordinated obligation of Accenture plc.

In this description:

10

The terms of each series of debt securities and guarantees, if applicable, will be established by or pursuant to a resolution of the issuer's board of directors and set forth or determined in the manner provided in a resolution of the issuer's board of directors, in an officer's certificate or by a supplemental indenture. The terms of any debt securities and, if applicable, the guarantees will include those stated in the applicable indenture and those made part of that indenture by reference to the Trust Indenture Act of 1939 (the "Trust Indenture Act"). The debt securities will be subject to all those terms, and we refer prospective purchasers and holders of debt securities and guarantees to the applicable indenture and the Trust Indenture Act for a statement of those terms. The debt securities will be described in a prospectus supplement relating to such series (including any pricing supplement or term sheet).

The following summaries of various provisions of the debt securities, the indentures and the guarantees are not complete. They do not describe certain exceptions and qualifications contained in the debt securities, the indentures and the guarantees, and are qualified in their entirety by reference to the provisions of the debt securities, the indentures and the guarantees. Unless we otherwise indicate, capitalized terms have the meanings assigned to them in the applicable indenture.

An applicable prospectus supplement will specify the issuer or co-issuers, the guarantor, if any, and whether the debt securities are to be guaranteed. The debt securities may be issued as part of units consisting of debt securities and other securities that may be offered under this prospectus. If debt securities are issued as part of units of debt securities and other securities that may be issued under this prospectus, an applicable prospectus supplement will describe certain applicable U.S. federal income tax considerations to holders.

General

The debt securities will be unsecured obligations of the applicable issuer. None of the indentures limit the amount of debt securities that the issuer may issue. Each indenture provides that the issuer may issue debt securities from time to time in one or more series.

The debt securities and any debt guarantees will be unsecured and unsubordinated obligations of the applicable issuer and will rank equally in right of payment with such issuer's other unsecured and unsubordinated obligations. Because Accenture plc is a holding company and Accenture Capital and Accenture DAC do not hold any assets, the holders of debt securities and debt guarantees may not receive assets of the applicable issuer's subsidiaries in a liquidation or recapitalization until the claims of such subsidiaries' creditors are paid, except to the extent that the applicable issuer may have recognized claims against such subsidiaries. In addition, certain regulatory laws limit some of such subsidiaries from making payments to the applicable issuer of dividends and on loans and other transfers of funds.

An applicable prospectus supplement will describe the specific terms relating to the series of debt securities being offered. These terms will include some or all of the following:

11

If an issuer denominates the purchase price of a series of debt securities in a non-U.S. dollar currency or currencies or a non-U.S. dollar currency unit or units, or if the principal of, any premium and interest on any series of debt securities is payable in a non-U.S. dollar currency or currencies or a non-U.S. dollar currency unit or units, an applicable prospectus supplement will generally describe certain U.S. federal income tax considerations applicable to such debt securities.

The issuer will pay principal and any interest, premium and additional amounts in the manner, at the places and subject to the restrictions set forth in the applicable debt securities, the applicable indenture and any applicable prospectus supplement. The issuer will not impose a service charge for any transfer or exchange of debt securities, but it may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed (or proof of payment thereof). (Section 2.05 of the indentures).

Unless otherwise indicated in an applicable prospectus supplement, each issuer will issue debt securities in fully registered form, without coupons, in denominations of $2,000 or integral multiples of $1,000 in excess thereof. (Sections 2.01 and 2.04 of the indentures).

The issuer may offer to sell at a substantial discount below their stated principal amount, debt securities bearing no interest or interest at a rate that, at the time of issuance, is below the prevailing market rate. An applicable prospectus supplement will generally describe certain U.S. federal income tax considerations applicable to any of those discounted debt securities.

12

The issuer may offer to sell debt securities in which the principal or interest will be determined by reference to one or more currency exchange rates, commodity prices, equity indices or other factors. The principal amount or payment of interest applicable to those debt securities may be greater than or less than the amount of principal or interest otherwise payable, depending upon the value of the applicable currency, commodity, equity index or other factor on the date on which that principal or interest is due. An applicable prospectus supplement will describe the methods used to determine the amount of principal or interest payable on any date, the currencies, commodities, equity indices or other factors to which the amount payable on that date is linked and certain additional tax considerations applicable to those debt securities.

The indentures do not restrict the issuer's ability to incur unsecured indebtedness or, unless specified otherwise in the applicable prospectus supplement, secured indebtedness, subject in all cases to the restrictions described in " -Consolidation and Merger," to engage in reorganizations, restructurings, mergers, consolidations or similar transactions that have the effect of increasing the issuer's indebtedness. Accordingly, unless an applicable prospectus supplement states otherwise, neither the debt securities nor any guarantees will contain any provisions that afford holders protection against the issuer or, if applicable, the guarantor incurring unsecured indebtedness or engaging in certain reorganizations or transactions. As a result, an issuer could become highly leveraged.

Events of Default

With respect to any series of debt securities, "event of default" means any of the following:

If there is a continuing event of default with respect to any outstanding series of debt securities, the applicable trustee or the holders of at least 25% of the outstanding principal amount of the debt securities of that series may require the issuer or, if applicable, the guarantor to pay immediately the principal (or, if the debt securities of that series are discount securities, that portion of the principal amount as may be specified in the terms of that series) of and accrued and unpaid interest, if any, on all debt securities of that series. However, at any time after that

13

trustee or the holders, as the case may be, declare an acceleration with respect to debt securities of any series, but before the applicable person has obtained a judgment or decree for payment of the money, the holders of a majority in principal amount of the outstanding debt securities of that series may, under certain conditions, cancel such acceleration if (i) all events of default (other than the non-payment of accelerated principal) with respect to such debt securities have been cured or (ii) all such events of default have been waived, each as provided in the applicable indenture. (Section 6.01 of the indentures). For information as to waiver of defaults, see " -Modification and Waiver." The particular provisions relating to acceleration of the maturity of a portion of the principal amount of such debt securities that are discount securities triggered by an event of default shall be described in an applicable prospectus supplement. In the event of bankruptcy, insolvency, liquidation or a similar event, the debt securities will become due and payable immediately and without any declaration or other act on the part of any holder.

Each indenture provides that, subject to the duties of the applicable trustee to act with the required standard of care, if there is a continuing event of default, the applicable trustee need not exercise any of its rights or powers under the indenture at the request or direction of any of the holders of debt securities, unless those holders have offered to the applicable trustee security or indemnity reasonably satisfactory to it. (Section 7.02 of the indentures). Subject to those provisions for security or indemnification of the applicable trustee and certain other conditions, the holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the applicable trustee or exercising any trust or power that trustee holds, in each case, with respect to the debt securities of that series. (Section 6.06 of the indentures).

No holder of any debt security of any series will have any right to institute any proceeding with respect to any indenture or for any remedy thereunder unless:

However, the holder of any debt security will have an absolute and unconditional right to receive payment of the principal of, and any premium or interest on, that debt security on or after the date or dates they are to be paid as expressed in or pursuant to that debt security and to institute suit for the enforcement of any such payment. (Section 6.04 of the indentures).

Each indenture provides that the applicable trustee shall provide notice to the holders of debt securities of any series within 90 days of the occurrence of any default with respect to such debt securities known to such trustee, except that the trustee need not provide holders of such debt securities notice of any default (other than the non-payment of principal or any premium, interest or additional amounts) if such default has been cured and such trustee considers it in the interest of the holders of such debt securities not to provide that notice. (Section 6.07 of the indentures).

Consolidation and Merger

Each indenture provides that each of the issuer and the guarantor may consolidate with or merge or convert into, or convey, transfer or lease its or their properties or assets substantially as an entirety to, another person without the consent of any debt security holders if, along with certain other conditions set forth in the indentures:

14

Notwithstanding the foregoing, (A) any conveyance, transfer or lease of assets between or among the guarantor or the issuer and its subsidiaries will not be prohibited under each indenture, and (B) each of the guarantor and the issuer may, directly or indirectly, consolidate with or merge with or into an affiliate incorporated solely for the purpose of reincorporating the guarantor or the issuer, as applicable, in another jurisdiction within the United States, any state thereof or the District of Columbia, Ireland, England and Wales, Jersey, any member state of the European Union as in effect on the date the debt securities of the applicable series are first issued or Switzerland to realize tax or other benefits. (Section 11.01 of the indentures).

Depending on the facts, it is possible that a merger, transfer, lease or other transaction could be treated for U.S. federal income tax purposes as a taxable exchange by the beneficial owner of debt securities or guarantees for new securities, which could result in U.S. beneficial owners of debt securities or guarantees recognizing taxable gain or loss for U.S. federal income tax purposes and possibly holding new notes with original issue discount solely for U.S. federal income tax purposes. A merger, transfer, lease or other transaction could also have adverse tax consequences to beneficial owners of debt securities or guarantees under other tax laws to which the beneficial owners are subject.

Payment of Additional Amounts

Payments made by Accenture plc, Accenture Capital, Accenture DAC or a paying agent, as applicable, on the debt securities or in respect of the guarantees will be made free and clear of and without withholding or deduction for or on account of any present or future income, stamp or other tax, duty, levy, impost, assessment or other governmental charge of a similar nature ("Taxes") unless Accenture plc, Accenture Capital, Accenture DAC or a paying agent, as applicable, is required to withhold or deduct Taxes by law or the official interpretation or administration thereof.

If Accenture plc, Accenture Capital, Accenture DAC or a paying agent, as applicable, is required to withhold or deduct any amount for or on account of Taxes from any payment made with respect to the debt securities or the guarantees levied by or on behalf of (i) the government of Ireland or by any authority or agency therein or thereof having the power to tax, (ii) any other jurisdiction in which Accenture plc, Accenture Capital or Accenture DAC is organized or is otherwise resident for tax purposes or any political subdivision or any authority or agency therein or thereof having the power to tax, or (iii) any jurisdiction from or through which payment under or with respect to Accenture plc, Accenture Capital or Accenture DAC is made or any political subdivision or any authority or agency therein or thereof having the power to tax, in each of clauses (ii) and (iii) other than the United States in the case of U.S. dollar-denominated debt securities issued by Accenture Capital (each of clauses (i), (ii), and (iii), a "Relevant Taxing Jurisdiction"), Accenture plc, Accenture Capital or Accenture DAC, as

15

applicable, will pay such additional amounts as may be necessary so that the net amount received by each holder (including additional amounts) after such withholding or deduction will not be less than the amount the holder would have received if the Taxes had not been withheld or deducted; provided that no additional amounts will be payable with respect to Taxes:

nor shall additional amounts be paid with respect to any payment of the principal of or premium, if any, or interest, if any, on any debt security or any payment in respect of any guarantee to any such holder or beneficial

16

owner who is a fiduciary or a partnership or a beneficial owner who is other than the sole beneficial owner of such payment to the extent a beneficiary or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner would not have been entitled to such additional amounts had it been the holder of the debt security. For the avoidance of doubt, no additional amounts shall be payable in respect of any Taxes imposed by any jurisdiction other than a Relevant Taxing Jurisdiction.

If Accenture plc, Accenture Capital, Accenture DAC or a paying agent becomes aware that it will be obligated to pay additional amounts pursuant to this covenant with respect to any payment with respect to a debt security or guarantee of the debt security, Accenture plc, Accenture Capital, Accenture DAC or a paying agent, as applicable, will deliver to the trustee on a date that is at least 30 days prior to the date of that payment (unless the obligation to pay such additional amounts arises after the 30th day prior to that payment date, in which case Accenture plc, Accenture Capital, Accenture DAC or a paying agent, as applicable, shall notify the trustee promptly thereafter) an officer's certificate of Accenture plc, Accenture Capital, or Accenture DAC stating the fact that such additional amounts will be payable pursuant to this covenant and the amount estimated to be so payable. Such officer's certificate must also set forth any other information reasonably necessary to enable the paying agents to pay such additional amounts to holders of the debt securities on the relevant payment date. The trustee shall be entitled to rely solely on such officer's certificate as conclusive proof that such payments are necessary. Accenture plc, Accenture Capital, Accenture DAC or a paying agent, as applicable, will provide the trustee with documentation reasonably satisfactory to the trustee evidencing the payment of additional amounts.

Accenture plc, Accenture Capital, Accenture DAC or a paying agent, as applicable, will make all withholdings and deductions required by law and will remit the full amount deducted or withheld to the Relevant Taxing Jurisdiction in accordance with applicable law with respect to payments in respect of the debt securities or guarantees. Upon request, Accenture plc, Accenture Capital, Accenture DAC or a paying agent, as applicable, will provide to the trustee an official receipt or, if official receipts are not obtainable, other documentation reasonably satisfactory to the trustee evidencing the payment of any Taxes so deducted or withheld. Upon request, copies of those receipts or other documentation, as the case may be, will be made available by the trustee to the holders of the debt securities.

The obligations in this covenant will survive any termination or discharge of the indenture and any transfer by a holder or beneficial owner of its debt securities and will apply mutatis mutandis to any jurisdiction in which any successor person to Accenture plc, Accenture Capital, Accenture DAC or a paying agent, as applicable, is incorporated or resident for tax purposes or any jurisdiction from or through which such person makes any payment in respect of the guarantees of such debt securities and any department or political subdivision thereof or therein.

All references in this prospectus, other than under " -Defeasance," to the payment of the principal of or premium, if any, or interest, if any, on or the net proceeds received on the sale or exchange of, any debt securities or any payment in respect of any guarantee shall be deemed to include additional amounts to the extent that, in that context, additional amounts are, were or would be payable. (Section 4.05 of the indentures).

Optional Tax Redemption

The issuer may redeem any series of debt securities in whole, but not in part, at its option at any time prior to maturity, upon the giving of not less than 10 nor more than 60 days' notice of tax redemption to the holders, at a redemption price equal to the principal amount plus accrued and unpaid interest, if any, to the redemption date (except in the case of discounted debt securities, which may be redeemed at the redemption price specified by the terms of each series of such debt securities), if:

17

No notice of any such redemption may be given earlier than 90 days prior to the earliest date on which Accenture plc, Accenture Capital or Accenture DAC, as applicable, would be obligated to pay any additional amounts.

Accenture plc, Accenture Capital or Accenture DAC will also pay to each holder, or make available for payment to each such holder, on the redemption date, any additional amounts (as described under " -Payment of Additional Amounts") resulting from the payment of such redemption price by it. Prior to the delivery of any notice of redemption, Accenture plc, Accenture Capital or Accenture DAC will deliver to the trustee (i) an officer's certificate stating that it is entitled to effect or cause a redemption and setting forth a statement of facts showing that the conditions precedent of the right so to redeem or cause such redemption have occurred, and (ii) an opinion of independent counsel to the effect that there has been such change or amendment that would entitle the issuer to redeem the debt securities under the indenture. The trustee will accept such officer's certificate and opinion of counsel as sufficient evidence of the existence and satisfaction of the conditions precedent as described above, in which event it will be conclusive and binding on the holders of the securities being redeemed. The foregoing will apply, mutatis mutandis, to any jurisdiction in which any successor to Accenture plc, Accenture Capital or Accenture DAC is incorporated or organized or tax resident or any political subdivision or taxing authority or agency thereof or therein, provided that if on the date of the succession the taxing jurisdiction is not already a Relevant Taxing Jurisdiction, the change or amendment of law becomes effective (or the announcement of the official interpretation is announced) after that date. (Section 3.02 of the indentures).

Defeasance

Defeasance and Discharge. Unless the debt securities of any series provide otherwise, the issuer and, if applicable, the guarantor may be discharged from any and all obligations in respect of the debt securities of that series and any related guarantee, as applicable (except for certain obligations to register the transfer or exchange of debt securities of that series, to replace stolen, destroyed, lost or mutilated debt securities of that series, to maintain paying agencies, to execute and furnish definitive securities evidenced by temporary securities, to return moneys deposited with or paid to the trustee or any paying agent remaining unclaimed for three years, to compensate and indemnify the applicable trustee or to furnish such trustee (if that trustee is not the registrar) with the names and addresses of holders of debt securities of that series). This discharge, referred to as defeasance, will occur only if, among other things:

18

That opinion must state that the issuer or, if applicable, the guarantor has or have received from the U.S. Internal Revenue Service a ruling or, since the date of execution of the applicable indenture, there has been a change in the applicable U.S. federal income tax law, in any case, in support of that opinion. (Sections 13.02 and 13.04 of the indentures).

In addition, the issuer or, if applicable, the guarantor or the issuer together with the guarantor may also obtain a discharge of the applicable indenture with respect to all debt securities issued under that indenture and any related guarantee, as applicable, by depositing with the applicable trustee, in trust, enough money to pay all amounts due on the debt securities on the date those payments are due or upon redemption of all of those debt securities, so long as those debt securities are by their terms to become due and payable within one year or are to be called for redemption within one year. (Section 12.01 of the indentures).

Defeasance of Certain Covenants and Certain Events of Default. Unless the debt securities of any series provide otherwise, upon compliance with certain conditions:

The conditions include, among other things:

19

Covenant Defeasance and Certain Other Events of Default. If the issuer or, if applicable, the guarantor or the issuer together with the guarantor exercises or exercise the option to effect a covenant defeasance with respect to the debt securities of any series as described above and the debt securities of that series are thereafter declared due and payable because of an event of default (other than an event of default caused by failing to comply with the covenants that are defeased), the amount of money and securities it has or they have deposited with the applicable trustee would be sufficient to pay amounts due on the debt securities of that series on their respective due dates but may not be sufficient to pay amounts due on the debt securities of that series at the time of acceleration resulting from that event of default. However, the issuer and, if applicable, the guarantor would remain liable for any shortfall.

Modification and Waiver

Each indenture provides that the issuer and, if applicable, the guarantor may enter into supplemental indentures with the applicable trustee without the consent of the holders of debt securities to:

The issuer and, if applicable, the guarantor may enter into a supplemental indenture to modify an indenture with the consent of the applicable trustee and the holders of at least a majority in principal amount of outstanding debt securities of each series affected by such supplemental indenture. However, the issuer and, if applicable, the guarantor may not modify an indenture without the consent of the holders of all then-outstanding debt securities of the affected series issued under that indenture to:

20

The holders of at least a majority in principal amount of the outstanding debt securities of any series may on behalf of the holders of all debt securities of that series waive any past default under the applicable indenture with respect to that series, except a default in the payment of the principal of or any premium or any interest on, any debt security of that series or in respect of a provision which under the applicable indenture cannot be modified or amended without the consent of the holder of each outstanding debt security of that affected series. (Section 6.09 of the indentures).

Global Securities

The debt securities of a series may be issued in whole or in part in the form of one or more global certificates that the issuer will deposit with a depositary identified in an applicable prospectus supplement. Unless and until it is exchanged in whole or in part for the individual debt securities that it represents, a global security may not be transferred except as a whole:

An applicable prospectus supplement will describe the specific terms of the depositary arrangement with respect to a series of debt securities. We anticipate that the following provisions will generally apply to depositary arrangements.

When a global security is issued, the depositary for the global security or its nominee will credit, on its book-entry registration and transfer system, the respective principal amounts of the individual debt securities represented by that global security to the accounts of persons that have accounts with the depositary ("participants"). Those accounts will be designated by the dealers, underwriters or agents with respect to the underlying debt securities or by the issuer if those debt securities are offered and sold directly by the issuer. Ownership of beneficial interests in a global security will be limited to participants or persons that may hold interests through participants. For interests of participants, ownership of beneficial interests in the global security will be shown on records maintained by the applicable depositary or its nominee. For interests of persons other than participants, that ownership information will be shown on the records of participants. Transfer of that ownership will be effected only through those records. The laws of some states require that certain purchasers of securities take physical delivery of securities in definitive form. These limits and laws may impair our ability to transfer beneficial interests in a global security.

As long as the depositary for a global security, or its nominee, is the registered owner of that global security, the depositary or nominee will be considered the sole owner or holder of the debt securities represented by the global security for all purposes under the applicable indenture. Except as provided below, owners of beneficial interests in a global security:

Payments of the principal of, any premium on and any interest on individual debt securities represented by a global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee as the registered owner of the global security representing such debt securities. No issuer, guarantor, trustee, paying agent or registrar for the debt securities will be responsible for any aspect of the records relating to or payments made by the depositary or any participants on account of beneficial interests in the global security.

21

It is expected that the depositary or its nominee, upon receipt of any payment of principal, any premium or interest relating to a global security representing any series of debt securities, immediately will credit participants' accounts with the payments. Those payments will be credited in amounts proportional to the respective beneficial interests of the participants in the principal amount of the global security as shown on the records of the depositary or its nominee. It is also expected that payments by participants to owners of beneficial interests in the global security held through those participants will be governed by standing instructions and customary practices. This is now the case with securities held for the accounts of customers registered in "street name." Those payments will be the sole responsibility of those participants.

If the depositary for a series of debt securities is at any time unwilling, unable or ineligible to continue as depositary and a successor depositary is not appointed within 90 days, the issuer will issue individual debt securities of that series in exchange for the global security or securities representing that series. In addition, the issuer may at any time in its sole discretion determine not to have any debt securities of a series represented by one or more global securities. In that event, the issuer will issue individual debt securities of that series in exchange for the global security or securities. Furthermore, if specified in an applicable prospectus supplement, an owner of a beneficial interest in a global security may, on terms acceptable to the issuer, the trustee and the applicable depositary, receive individual debt securities of that series in exchange for those beneficial interests. The foregoing is subject to any limitations described in an applicable prospectus supplement. In any such instance, the owner of the beneficial interest will be entitled to physical delivery of individual debt securities equal in principal amount to the beneficial interest and to have the debt securities registered in its name. Those individual debt securities will be issued in any authorized denominations.

Guarantees

Under the guarantee, the applicable guarantor will fully and unconditionally guarantee the due and punctual payment of the principal, interest (if any), premium (if any) and all other amounts due on the applicable debt securities and under the indenture when the same shall become due and payable, whether at maturity, pursuant to mandatory or optional redemption or repayments, by acceleration or otherwise, in each case after any applicable grace periods or notice requirements, according to the terms of the applicable debt securities.

The obligations of the guarantor under the guarantee will be full and unconditional, joint and several, regardless of the enforceability of the applicable debt securities, and will not be discharged until all obligations under those debt securities and the applicable indenture are satisfied. Holders of the applicable debt securities may proceed directly against the guarantor under the applicable guarantee if an event of default affecting those debt securities occurs without first proceeding against the issuer.

Conversion Rights

An applicable prospectus supplement will describe the terms and conditions, if any, on which debt securities being offered are convertible into Class A ordinary shares of Accenture plc or other securities. Such terms will include the conversion price, the conversion period, provisions as to whether conversion will be at the option of the issuer or the holder, the events requiring an adjustment of the conversion price and provisions affecting conversion in the event of the redemption of such debt securities.

Regarding the Trustee

The issuers have commercial deposits and custodial arrangements with The Bank of New York Mellon Trust Company, N.A. ("BNY") and may have borrowed money from BNY in the normal course of business. The issuers may enter into similar or other banking relationships with BNY in the future in the normal course of business. BNY may also act as trustee with respect to other debt securities issued by the issuers.

22

BNY will be serving as the trustee under the indentures. Consequently, if an actual or potential event of default occurs with respect to the debt securities, BNY may be considered to have a conflicting interest for purposes of the Trust Indenture Act. In that case, BNY may be required to resign under one or more indentures, and the applicable issuer and, if applicable, the applicable guarantor would be required to appoint a successor trustee. For this purpose, a "potential" event of default means an event that would be an event of default if the requirements for giving us default notice or for the default having to exist for a specific period of time were disregarded.

Governing Law

The debt securities, the guarantees and the indentures will be governed by and construed in accordance with the laws of the State of New York.

23

DESCRIPTION OF SHARE PURCHASE CONTRACTS AND SHARE PURCHASE UNITS OF ACCENTURE PLC

Accenture plc may issue share purchase contracts, representing contracts obligating holders to purchase from Accenture plc, and obligating Accenture plc to sell to the holders, a specified number of its Class A ordinary shares at a future date or dates.

29

PLAN OF DISTRIBUTION

Accenture plc, Accenture Capital or Accenture DAC may sell the securities covered by this prospectus in any of the following ways (or in any combination):

Any such dealer or agent, in addition to any underwriter, may be deemed to be an underwriter within the meaning of the Securities Act. Any discounts or commissions received by an underwriter, dealer, remarketing firm or agent on the sale or resale of securities may be considered by the SEC to be underwriting discounts and commissions under the Securities Act.

In addition, Accenture plc, Accenture Capital or Accenture DAC may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If an applicable prospectus supplement so indicates, in connection with such a transaction, the third parties may, pursuant to this prospectus and such applicable prospectus supplement, sell securities covered by this prospectus and such applicable prospectus supplement. If so, the third party may use securities borrowed from Accenture plc, Accenture Capital, Accenture DAC or others to settle such sales and may such securities to close any related short positions. Accenture plc, Accenture Capital or Accenture DAC may also loan or pledge securities covered by this prospectus and an applicable prospectus supplement to third parties, who may sell the loaned securities or, in an event of default in the case of a pledge, sell the pledged securities covered by this prospectus and such applicable prospectus supplement.

The terms of the offering of the securities with respect to which this prospectus is being delivered will be set forth in the applicable prospectus supplement or supplements and will include, among other things:

If underwriters are used in the sale of securities, those securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The securities may be offered to the public either through underwriting syndicates represented by managing underwriters or directly by one or more underwriters acting alone. Unless otherwise set forth in an applicable prospectus supplement, the obligations of the underwriters to purchase the securities described in an applicable prospectus supplement will be subject to certain conditions precedent, and the underwriters will be obligated to purchase all of those securities if any are purchased by them. Any public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

30

If the dealers acting as principals are used in the sale of any securities, those securities will be acquired by the dealers, as principals, and may be resold from time to time in one or more transactions at varying prices to be determined by the dealer at the time of resale. The name of any dealer and the terms of the transactions will be set forth in an applicable prospectus supplement with respect to the securities being offered.

Securities may also be offered and sold, if so indicated in an applicable prospectus supplement in connection with a remarketing upon their purchase, in accordance with a redemption or repayment pursuant to their terms, or otherwise, by one or more firms, which we refer to as the "remarketing firms," acting as principals for their own accounts or as our agents, as applicable. Any remarketing firm will be identified and the terms of its agreement, if any, with Accenture plc, Accenture Capital or Accenture DAC and its compensation will be described in an applicable prospectus supplement. Remarketing firms may be deemed to be underwriters, as that term is defined in the Securities Act in connection with the securities remarketed thereby.

The securities may be sold directly by Accenture plc, Accenture Capital or Accenture DAC, or through agents designated by one of them from time to time. In the case of securities sold directly by Accenture plc, Accenture Capital or Accenture DAC, no underwriters or agents would be involved. Any agents involved in the offer or sale of the securities in respect of which this prospectus is being delivered, and any commissions payable by Accenture plc, Accenture Capital or Accenture DAC to such agents, will be set forth in an applicable prospectus supplement. Unless otherwise indicated in an applicable prospectus supplement, any such agent will be acting on a best efforts basis for the period of its appointment.

Accenture plc, Accenture Capital or Accenture DAC may authorize agents, underwriters or dealers to solicit offers by certain specified institutions to purchase the securities to which this prospectus and the applicable prospectus supplement relate from us at the public offering price set forth in an applicable prospectus supplement plus, if applicable, accrued interest, pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. Those contracts will be subject only to those conditions set forth in an applicable prospectus supplement, and an applicable prospectus supplement will set forth the commission payable for solicitation of those contracts.

Agents, dealers, underwriters and remarketing firms may be entitled, under agreements entered into with one or more of Accenture plc, Accenture Capital or Accenture DAC, to indemnification by one or more of Accenture plc, Accenture Capital or Accenture DAC against certain civil liabilities, including liabilities under the Securities Act, or to contribution to payments they may be required to make in respect thereof. Agents, dealers, underwriters and remarketing firms may be customers of, engage in transactions with, or perform services for us or our subsidiaries in the ordinary course of business.

Unless otherwise indicated in an applicable prospectus supplement, all securities offered by this prospectus, other than the Class A ordinary shares of Accenture plc, which are listed on the New York Stock Exchange, will be new issues with no established trading market. Accenture plc, Accenture Capital or Accenture DAC, as applicable, may elect to list any of the securities on one or more exchanges, but unless otherwise specified in an applicable prospectus supplement, shall not be obligated to do so. In addition, underwriters will not be obligated to make a market in any securities. No assurance can be given regarding the activity of trading in, or liquidity of, any securities.

Any underwriter may engage in over-allotment, stabilizing transactions, short-covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Over-allotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying securities so long as the stabilizing bids do not exceed a specified maximum. Short covering transactions involve purchases of the securities in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a covering transaction to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time.

31

VALIDITY OF SECURITIES

Unless otherwise indicated in an applicable prospectus supplement, the validity of the securities under Irish law will be passed upon for us by Arthur Cox LLP and certain matters with respect to New York law will be passed upon for us by Gibson, Dunn & Crutcher LLP. Any underwriters, dealers or agents may be advised about other issues relating to any offering by their own legal counsel.

EXPERTS

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution.

The following is a statement of the estimated expenses to be incurred in connection with the issuance and distribution of the securities being registered, other than underwriting discounts, commissions and transfer taxes, to be paid by the Registrant. The following statement of estimated expenses has been used to demonstrate the expense of an offering and does not represent an estimate of the aggregate amount of securities that may be registered or distributed pursuant to this registration statement because such amount is unknown at this time. Information regarding estimated expenses of issuance and distribution of each identified class of securities being registered will be provided at the time of issuance thereof.

Item 15. Indemnification of Directors and Officers.

Accenture plc

If an officer (within the meaning of Irish law, which includes the directors. the secretary and assistant secretaries) of an Irish company is found to have breached his or her fiduciary duties to that company, he or she may be held personally liable to the company in respect of that breach of duty. Accenture plc's articles of association contain indemnification and expense advancement provisions for persons who are not officers (within the meaning of Irish law) of Accenture plc. Accenture plc's articles of association also confer a more limited indemnity on its officers (within the meaning of Irish law) for certain costs and discharge the liability of such officers where judgment is given in favor of any such officer in any civil or criminal action in respect of such costs or liability, or where an Irish court grants relief because any such officer acted honestly and reasonably and ought fairly to be excused. This restriction does not apply to executives or officers who are not officers (within the meaning of Irish law) of Accenture plc. Any provision which seeks to indemnify an officer (within the meaning of Irish law) of an Irish company over and above this shall be void under Irish law, whether contained in its articles of association or any contract between such officer and the company.

Under Irish law, Accenture plc may not exempt its officers (within the meaning of Irish law) from liability for negligence or a breach of duty. However, where a breach of duty has been established, such officers may be statutorily exempted by an Irish court from personal liability for negligence or breach of duty if, among other things, the court determines that they have acted honestly and reasonably, and that they may fairly be excused as a result.

In accordance with Irish law, Accenture plc has taken out directors and officers liability insurance, as well as other types of insurance, for our directors and officers.

In addition, Accenture Inc., a Delaware corporation and a direct, controlled subsidiary of Accenture plc, has entered into indemnification agreements with each of the Accenture plc's directors providing for the indemnification of, and advancement of expenses to, these persons.

Accenture Capital

Accenture Capital was organized under and is subject to the Delaware General Corporation Law. Delaware law provides that officers and directors may receive indemnification from their corporations for certain actual or threatened lawsuits. Delaware law sets out the standard of conduct which the officers and directors must meet in order to be indemnified, the parties who are to determine whether the standard has been met, and the types of expenditures which will be indemnified. Delaware law further provides that a corporation may purchase indemnification insurance, such insurance providing indemnification for the officers and directors whether or not the corporation would have the power to indemnify them against such liability under the provisions of Delaware law.

Article IV of Accenture Capital's Bylaws (the "Accenture Capital Bylaws") provides that, the extent permitted by the Delaware General Corporation Law, Accenture Capital will indemnify its current or former directors or officers and may, at the discretion of its board of directors, indemnify any of its current or former employees or agents against all expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred him or her in connection with any threatened, pending or completed action, suit or proceeding brought by the right of Accenture Capital or otherwise, to which he or she was or is a party by reason of his or her current or former position with Accenture Capital or by reason of the fact that he or she is or was serving, at the request of Accenture Capital, as a director, officer, partner, trustee, employee or agent of another corporation, partnership, joint venture, trust or other enterprise.

Furthermore, Accenture Capital is covered by insurance which will reimburse it within the policy limits for amounts it is obligated to pay in lawsuits involving officers and directors serving in such capacities in which the damages, judgments, settlements, costs, charges or expenses incurred in connection with the defense of the action, suit or proceeding are reimbursable pursuant to law and the Accenture Capital Bylaws.

Accenture Capital expects that any underwriting agreement or distribution agreement relating to the securities will provide for indemnification of directors and officers of Accenture Capital by the underwriters or agents, as the case may be, against certain liabilities.

Accenture Capital has also entered into separate indemnification agreements with certain of its officers, which agreements provide specific contractual assurance with respect to the existing indemnification and expense advancement rights extended to such officers and directors under Article IV of the Accenture Capital Bylaws. Specifically, the indemnification agreements provide assurance that no future amendment to or revocation of the Accenture Capital Bylaws will adversely affect any existing right of an officer or director with respect to any event that occurred prior to such amendment or revocation (regardless of when any proceeding related to such event is first threatened, commenced or completed).

The directors of Accenture Capital will also be entitled to cover pursuant to the Accenture group's directors' and officers' liability insurance.

Accenture DAC

If an officer (within the meaning of Irish law, which includes the directors. the secretary and assistant secretaries) of an Irish company is found to have breached his or her fiduciary duties to that company, he or she may be held personally liable to the company in respect of that breach of duty. Accenture DAC's articles of association

II-2

contain indemnification and expense advancement provisions for persons who are not officers (within the meaning of Irish law) of Accenture DAC. Accenture DAC's articles of association also confer a more limited indemnity on its officers (within the meaning of Irish law) for certain costs and discharge the liability of such officers where judgment is given in favor of any such officer in any civil or criminal action in respect of such costs or liability, or where an Irish court grants relief because any such officer acted honestly and reasonably and ought fairly to be excused. This restriction does not apply to executives or officers who are not officers (within the meaning of Irish law) of Accenture DAC. Any provision which seeks to indemnify an officer (within the meaning of Irish law) of an Irish company over and above this shall be void under Irish law, whether contained in its articles of association or any contract between such officer and the company.

Under Irish law, Accenture DAC may not exempt its officers (within the meaning of Irish law) from liability for negligence or a breach of duty. However, where a breach of duty has been established, such officers may be statutorily exempted by an Irish court from personal liability for negligence or breach of duty if, among other things, the court determines that they have acted honestly and reasonably, and that they may fairly be excused as a result.

The directors of Accenture DAC will also be entitled to cover pursuant to the Accenture group's directors' and officers' liability insurance.
